Five book series written by award winning author Rick Riordin. Other work by same Author include the well known books turned movies from the Percy Jackson Series (not included with this set) This book series is very similar to that of his Percy Jackson series but with different characters to fall in love with, and new exciting adventures to watch unfold before your very eyes! The books are in excellent condition, with the only wear being on the first book, a small spot is seen on the bottom corners of the first few pages. The box also has a little wear from simply sitting around and also moved from one home to our new one. Perfect for young teens and adults as well!
